Ad Space and Sponsorship: Information:

To sponsor something is to support an event, activity, person, or organization financially or through the provision of products or services. 

A sponsor is the individual or group that provides the support, similar to a benefactor

Sponsorship typically benefits both the recipient (by providing material benefits) as well as the sponsor (as a marketing tool that enhances the sponsor's public image and provides access to a wider audience).

Sponsorship may be an arrangement to exchange advertising for the responsibility of funding a popular event or entity. For example, a corporate entity may provide equipment for a athletes or sports team in exchange for brand recognition

The sponsor earns popularity this way while the sponsored can save on cost. This type of sponsorship, known as cause-related, is prominent in the sports, arts, media and charity sectors.
